I only use RM43 on grass that grows in my driveway and around the perimeter of my house to keep from weedeating, so I can’t specifically answer your question. However, I would be afraid to use it in a food plot.About this. I see the RM43 at Atwoods when I go look for the glyphosate I normally use. Question for ya. I mow my plots really low about early August. Let the weeds and other crap start to grow back up until about early Sept then spray glyphosate on them. Ideally, let it kill off everything for 10 days to two weeks. Then on one weekend will rototill with my tractor, drag it and reseed with what I want to plant that year for the deer food plot. If I were to use the RM43 would it last too long and also kill off the food plot seed I plant or would I be OK like when using the glyphosate? Last food plot prep season I got behind and rototilled about a week after applying the glyphosate and the food plots grew like crazy so the so the herbicide didn't affect the new seed I put down. Same with RM43 or does it last in the soil much longer?
This isn’t on topic, but I’m going to express my opinion on spraying food plots since you brought it up.
I don’t see the point. If I was planting a grain crop to harvest later, I’d spray, but for a seasonal “deer” food plot, it’s a waste of time and money in my opinion. I’ve planted a bunch of food plots and been really successful using till and no till methods, and I’ve never sprayed a chemical on any of them.
